To aZZ who/m. t may concern.'

Be it known that I, CHARMS A. HARMs, a citizen of the United States, and a resident of Indianapolis, county of Marion, and State of Indiana, have invented a new and useful Improvement in Typograph Mechanism, of which the following is a specification, the principle of the invention being herein explained and the best mode in which l have l0 contemplated applying that principle, so as to distinguish it from other inventions.

The present improvements, relating, as indicated, to typograph mechanism, have more particular regard to holders for matrix bars,

l5 such as are employed in the so-called Ludlow typograph (see U. S. Letters Patent No. 1,266,156, to William A. Reade, dated May 14, 1918.) ln such typograph, the holder is an independent member arranged to receive l0 and hold a number of detached matrix bars in selected relation, thereby forming acomposite matrix apart from, but adapted to cooperate with, a lmold when said holder 1s temporarily secured to a suitable support. The detached matrix bars, or matrices as they are ordinarily called, are ineiect plates or blocks of uniform length and height, but of varying width to accommodate character impressions of correspondingly varyingy width, such` haracter impresslons being struck or driven in the bottom of recesses cut in what may be called the lower edges of the bars. Where it has been desired to have a blank space in or at the end of the printed line, it has heretofore been the practice to sim ly insert one or more blank matrices of tlie proper width and of such depth that the corresponding portion of the casting face of the slug is lower in height than the ty e 4 characters thereon, and thus will not he inked or impressed. Such blank matrix bars correspond, in other words, with the familiar quadrat, or quad of the typesetter.

However, to lill out part lines at the ends of paragraphs, and in other connections, as well as for casting lines completely blank, unnecessary labor is involved in thus assembling and disassembling such blank matrix bars or Lquads The object of the present 0 invention, accordingly, is to provide such a holder, or stick as it is more familiarly called, which will be selfquadding, i. e., one wherein the left-over portion or the entire line may be instantly blanked off' without the insertion of such special matrix bars, and yet not interfere with the inclusion of as many matrix bars bearing character impressions at the left of the line as may be re aired.

' l.To the accomplishment of the (foregoing and related ends, the invention, then,'con sists of the means hereinafter :fully described and particularly pointed out in the claims, therannexed drawing and the following description setting forth in detail certain mechanism embodying the invention, such disclosed means constituting, however, but several of the various mechanical forms in whiich the principle of the invention may be use in said annexed drawing Fig. 1 is a perspective view of a holder or stick adapted for employment in the Ludlow typograph, such holder having incorpo rated therein the self-quadding feature just referred to; Fig. 2 is a central longitudinal section of such holder; Fig. 3 is a transverse section thereof, taken on the plane indicated.

by the line 3 3, Fig. 2; Fig. 4 is a plan view of a slightly modified construction: Fig. 5 is a. central longitudinal section thereof; and Fig. 6 is a transverse section of such modi-A fied construction, taken on the plane indicated by the line 6 6, Fig. 4.

Referring first of all to the construction illustrated in the first three figures of the drawing, the holder will be seen to comprise two end-pieces 1, lsecured to side members 2, 2 of suiiicient length to provide an opening somewhat longer than the maximum length of the slug which it isV desired to castq one of said end-pieces (the one at the left end in Fig. 1) being detachable to facilitate assembly of the device. Slidably mounted between said side members is a bar 3 of the cross-sectional form best shown in Fig. 3, and of length suflicient to ll, if desired, the entire space between said side members. This bar is shown as formed with an undercut groove 4f on its upper face, such groove extending substantially its entire length, and receiving the head 5 of a clamp screw 6, the threaded body of which projects upwardly through da suitable hole 7 in the one end-piece 2 to receive a knurled nut 8. ln order to hold the nut in place, it is formed With a shoulder 9 that is engaged by a bar l() attached to the side members 2, 2. The inner end of such slidable member 3 is preferably provided with an abutment 11, whereby any character-impression bearing matrix bars 12 (ses Fig. 2) may be forced into a compact assembly at the left of the holder or stick When the'space between the side members is thus filled, either wholly by saidbar 4 or by the latter in part and such an assemblage of matrix bars in part, the bar is clamped in p place by turning the nut 8, as will be readily understood, whereupon a slug may be cast from the under face of the composite matrixv thus provided.

In the modified construction shown in Figs. 4, 5 and 6, the holder consists, as bei fore, of two end-pieces 13, 13secured to side members 14, 14. The slidable bar, however, which here constitutes the self-quadding element is composed of two narrow plates 17 and 18 which lie in close fitting contact with the Aone endepiece 13, the one below, the other above, as best, shown in Fig. 5. These plates are held together in properly spaced vertical relation, and at the same time are secured to the stick thus composedl of end-pieces 13, 13 and side members 14, 14, by means of two blocks 19 and 20 inserted between their respective ends, such plates being screwed or riveted to such blocks. rlhe inner block 20, as shown in Fig. 6, lits slidably between side members 14, 14, and the assembly of parts including said plates 17 and 18 is further guided in its movement longitudinally of said side members by means of a rod 21 secured at its .respective ends to the blocks 19 and 20, and passing throu h a hole 22.in end-piece 13. The outer en of this rod projects beyond the corresponding block 19, and has attached thereto a knob 23 for the convenience of the operator in longitudinally adjusting the slide as a whole.

The manner of use of this lastdescribed form of the device is substantially the same as of the first. In other words, if ,desired the slide can be advanced to the left so as to entirely iill the space between the side members 14, 14, or, as shown in Fig. 5, to fill the space left over after such space has been partly filled with an assemblage of matrix-bars 12. The upper plate 18, it will be observed, lies flush with the upper faces of said matrix-bars, just as the under face 17 lies iush with their underafaces.` Accordingly, with the parts as shown in Fig. 5, for example, the composite matrix thus provided, may be vertically clamped in a casting mechanism of' the sort described in the aforesaid Patent No. 1,266,156, without it being necessary to laterally clamp the bars and quadding element in place.

Either of the foregoing constructions, it will be observed, provides what has been referred to as a self-quadding stick, in that it is unnecessary to employ blank ma.-`

` trix-bars to fill out the line, nor is it necessary to calculate the residual space in order te select just the right number and sizes of incassa such blank matrix-bars, since the uadding element is obviously instantly a justable. At the same time if it is desired to cast a slug with itsv entire face blank, by leaving out an matrix-bars and moving the quadding e ement inwardly to its limiting position, a blank matrix is provided.

Other modes of applying the principle of my invention may be employed instead of the one explained, change being made as regards the mechanism herein disclosed, provided the means stated by an of the following claims or the equiva ent of such stated means be employed.

. I therefore particularlypoint out and distinctly claim as my invention 1. A holder for matrix-bars of the character described, comprisin an independent member formed with an e ongated opening adapted to receive a number of such bars transversel disposed therein, and a bar disposed longitudinally of the opening in said member and movably secured to the latter so as to be adapted to quad out any desired portion of such openin 2. A holder for matrix-bars of the character described, comprising an independent member formed with an elongated opening adapted to receive a number of such bars transversel disposed therein, and a bar disposedl longltudinall of the opening in said member and slidably secured to one end of the latter so as to be adapted to quad out any desired portion of such opening.

3. A holder for matrix-bars of the character described, comprising end-pieces and side members attached thereto so as to provide an elongated o ening adapted to receive a number of such bars transversely disposed therein, a block slidabl fitting in such opening, and two barsl dlisposed one above and the other below one such endpiece and attached at their inner ends to said block.

4. A 'holder for matrix-bars of the character described, comprising end-pieces and side members attached thereto so as to provide an elongated opening adapted to receive a number of such bars transversely disposed therein, a block slidably fitting in such opening, two bars disposed one above and the other below one such end-piece and attached at their inner ends to said block, and a second block secured to the outer end of said bars.
